he galls. The mature pupa (examined 15th Juno) was l^-lin. long, its 
orax, and all appendages pitchy-black, shining; abdomen dull tile-red, its

Lon emerging, the pupa forces its way out of the gall by a series of wriggling, 
novcments, until about half of its length is disengaged; the usual process 
ting tho back of the thorax in a horizontal and afterwards vertical direction, 
as tho gradual freeing of the head and limbs follow; and, when quite 
id, the imago discharges a drop of milky hquid.

How female of CoUas Eyale.-ln a letter which I received a short time since 
olonol H. Macchio, of Vienna, he says,-" I have reserved a yellow female 
Eyale for you." I believe many of these yellow females have been passed 
this country for males, as, among the small number of specimens of this 
ay which I saw last year (not more than thirty or forty), I found four of 
The ordinary female of Colias Palxno is white ; but I have three of the

n the larva of Pyralis glaucmaUs.-To the Hon. T. de Grey I am indebted 
, opportunity of figuring and describing the larva of this species, he having 
it in the manner he has detailed in the following note :— 
Thinking that the nest-like bunches of twigs, which may often be observed 
ring at the ends of branches on birch trees, might perhaps be tenanted by 
e larva, or pupae, I obtained one of these knots in April, 1867, and placed it 
large breeding cage, where I soon observed a few black active -looking larv», 
some old cocoons containing empty pupa skins. 
•Havin- no conjecture as to what species these belonged to, I was much 
,rested by obserring on the 10th of June, a specimen of Pyralis glaucinalis at 
side of tho breeding cage ; others continued to appear, and on June the 13th, 
ad a note in my diary, « Larva), pupa), and imago of glaucinalis all ahve at 
le time.' , , , • •. 
='0n the 24th of June, I took out the knot, and by shaking and beating it 
ained from it twelve specimens which were by no means easily dislodged. 
"The species continued to appear throughout June and part of July, till about 
ty specimens in all were bred from this one large birch knot. 
« This year (1869) I again obtained knots from the same looahty as before, 
1 found them to contain old cocoons, and larva) of the same species in various 
,ges of growth ; from these I bred a few specimens of the perfect msect about 
3 middle of July.
